Type material. Holotype: female, Russia, “Stavropol’skiy kray, Shpakovskoe, sukhoy lug [dry meadow], 10.07.1988, Belokobylskij” ( ZISP).

Description. Female. Body length 2.30 mm.

Head (dorsal view) 1.50 times as wide as median length, 1.50 times as wide as mesosoma at level of tegulae. Head behind eyes distinctly roundly narrowed. Transverse diameter of eye 1.60 times longer than temple (dorsal view). Ocelli small, almost in equilateral triangle. POL about 2.00 times Od, 0.40 times OOL. Antennal socket diameter almost equal to distance between sockets, 1.30 times distance between socket and eye. Eye with short and sparse setae, with very fine emargination opposite antennal socket, 1.25 times as high as broad. Malar space 0.40 times as high as eye, 1.20 times as high as basal width of mandible. Malar suture absent. Face and clypeus distinctly convex, width of face 1.10 times eye height and 1.20 times height of face and clypeus combined. Hypoclypeal depression round, width almost equal to distance from depression to eye, 0.45 times width of face. Occipital carina complete dorsally, not arched to ocelli medio-dorsally, almost joined ventrally with hypostomal carina above base of mandible. Hypostomal flange rather distinct. Head below eyes distinctly and weakly roundly narrowed (frontal view).

Antenna thick, filiform, with 16 flagellomeres, 0.80 times as long as body. Scape rather short and thick, 1.40 times longer than maximum width, 1.20 times longer than pedicel. First flagellomere almost 2.00 times longer than apical width, as long as second flagellomere; second flagellomere 1.80 times longer than width. Penultimate flagellomere 1.80 times longer than wide, 0.90 times as long as first flagellomere, as long as apical flagellomere; the latter weakly pointed apically and without spine.

Mesosoma more or less reduced in size, length 1.80 times height. Pronotum rather long, convex dorsally, anterior margin weakly concave (dorsal view), pronotal keel almost absent. Mesoscutum distinctly and gradually roundly elevated above pronotum, 0.85 times as long as maximum width. Notauli distinct, rather deep, more or less wide, complete, rugulose-granulate; without furrow on median lobe. Prescutellar depression relatively deep, long, with single median carina, distinctly and densely strigate-rugulose. Scutellum separated, with distinct lateral carinae. Subalar depression relatively shallow, wide, granulate-strigate. Precoxal suture present, distinct, densely crenulate-rugose, running along anterior 0.55 of lower part of mesopleuron. Prepectal carina distinct. Postpectal carina absent. Metapleural lower lobe short, more or less wide, rounded apically. Propodeum more or less regularly convex-roundly narrowed posteriorly (lateral view), without lateral tubercles and postero-lateral carinae. In dorsal view, mesonotum 4.70 times longer than pronotum, 2.30 times longer than propodeum. Tegulae present.

Wings. Size of wings distinctly reduced, wings narrow, subpointed apically, with distinct venation in basal part, without sclerotized areas, reaching middle of propodeum.

Legs. Femora more or less slender. Hind femur 4.10 times longer than maximum width. Hind tarsus 0.90 times as long as hind tibia. Hind tibia weakly widened posteriorly. Claws distinctly curved.

Metasoma 1.70 times longer than maximum width, 0.80 times longer than head and mesosoma combined. First tergum distinctly and rather regularly widened from base to apex, with dorsal carinae widely separated, complete, weakly curved for most of length but distinctly curved apically; length of tergum 0.70 times apical width, almost equal to length of propodeum; apical width of tergum 1.80 times minimum basal width. Groove between second and third terga distinct, wide, weakly curved. Second tergum with sublateral oblique furrows shallow or very shallow posteriorly and almost parallel to lateral margins of tergum. Median length of second tergum 1.10 times longer than apical width of first tergum, 1.70 times length of third tergum. Median length of second and third terga combined 0.85 times maximum width. Ovipositor straight, sheath almost as long as first metasomal tergum, 0.30 times as long as hind tibia, 0.25 times as long as mesosoma.

Sculpture and pubescence. Vertex densely and distinctly granulate, additionally with distinct areolate-rugosity, with short rugae along occipital carina; frons densely granulate, partly with fine rugulosity; face distinctly and densely granulate and partly with fine rugosity, narrow area nearly smooth medially; temple distinctly, entirely, and densely granulate with rather fine rugosity. Mesoscutum entirely, distinctly, and densely granulate, with short rugosity anteriorly along notauli, finely granulate posteriorly. Scutellum rather distinctly granulate. Mesopleuron finely granulate-coriaceous, with distinctly curved carination dorsally and postero-ventrally, smooth in submedian areas. Propodeum entirely rugose-areolate, with dense granulation basally; with rather distinctly delineated areola and unclearly separated short petiolate area; areola rather long and wide, about twice longer than maximum width, almost fused anteriorly with base of propodeum. Hind femur more or less smooth, finely rugulose-carinate dorsally. First tergum almost entirely smooth, with very fine carination or rugulosity basolaterally and along dorsal carinae. Terga posterior to first tergum smooth, without punctation. Vertex with sparse, short, and semi-erect pale setae. Mesonotum with rather sparse, short, semi-erect pale setae along notauli and laterally. Hind tibia dorsally with dense, short, and semi-erect setae, length of those setae 0.50–0.60 times maximum width of hind tibia.

Color. Head, mesosoma mostly, and metasoma basally and apically reddish brown to dark reddish brown, prothorax almost yellow, metasoma widely medially yellowish brown. Antenna brownish yellow in basal 0.40, brown to dark brown in apical 0.60. Palpi yellow. Legs yellow basally, mostly light reddish brown, hind tibia pale basally. Ovipositor sheath dark reddish brown.

Male. Unknown.

Diagnosis. This new species is very similar to H. minialatus but differs as follows: first metasomal tergum almost entirely smooth, head more strongly narrowed behind eyes, and vertex granulate and without rugulosity. Distribution. Russia (Stauropol’ Territory).
